Merge tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 bugfixes from Ted Ts'o: "These changes contains a fix for overlayfs interacting with some (badly behaved) dentry code in various file systems. These have been reviewed by Al and the respective file system mtinainers and are going through the ext4 tree for convenience. This also has a few ext4 encryption bug fixes that were discovered in Android testing (yes, we will need to get these sync'ed up with the fs/crypto code; I'll take care of that). It also has some bug fixes and a change to ignore the legacy quota options to allow for xfstests regression testing of ext4's internal quota feature and to be more consistent with how xfs handles this case" * tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: ext4: ignore quota mount options if the quota feature is enabled ext4 crypto: fix some error handling ext4: avoid calling dquot_get_next_id() if quota is not enabled ext4: retry block allocation for failed DIO and DAX writes ext4: add lockdep annotations for i_data_sem ext4: allow readdir()'s of large empty directories to be interrupted btrfs: fix crash/invalid memory access on fsync when using overlayfs ext4 crypto: use dget_parent() in ext4_d_revalidate() ext4: use file_dentry() ext4: use dget_parent() in ext4_file_open() nfs: use file_dentry() fs: add file_dentry() ext4 crypto: don't let data integrity writebacks fail with ENOMEM ext4: check if in-inode xattr is corrupted in ext4_expand_extra_isize_ea()
